Cancer Metastasis Reviews
|January 27, 2011
Summary
This review examines if morphine, a common pain reliever, affects cancer metastasis. Research is ongoing to clarify morphine
Area of Science:
- Oncology
- Pharmacology
- Immunology
Background:
- Opioids, including morphine, are frequently used for cancer pain management.
- Concerns exist regarding opioid effects on cancer recurrence and metastasis.
- Existing literature presents conflicting findings on whether opioids promote or inhibit cancer spread.
Purpose of the Study:
- To review current data on morphine's influence on cancer metastasis and recurrence.
- To explore potential mechanisms, such as immunomodulation and tumor cell behavior.
- To reconcile discrepancies in published research regarding morphine's impact on cancer.
Main Methods:
- Comprehensive review of published clinical and laboratory-based studies.
- Analysis of data on immunomodulation, tumor cell aggressiveness, and angiogenesis.
- Investigation of factors contributing to conflicting study results.
Main Results:
- Morphine's effects on cancer metastasis are complex and debated.
- Evidence suggests potential roles in immune response modulation and tumor cell pathways.
- Angiogenesis and tumor cell aggressiveness are key areas of investigation.
Conclusions:
- Further research is crucial to definitively determine morphine's impact on cancer metastasis.
- Understanding the discrepancies in current literature is essential for clinical practice.
- Clarifying morphine's role is vital for optimizing cancer pain management and patient outcomes.

01:20Opioid Analgesics: Morphine and Other Natural Cogeners
Opioids are a class of drugs that mimic endogenous opioid peptides and act on opioid receptors, and help in pain relief. These compounds are classified as natural, synthetic, or semi-synthetic. Natural opioids, like morphine, codeine, and thebaine, are derived from the opium poppy plant (Papaver somniferum or Papaver album) and are termed opiates. Synthetic opioids are artificial, while semi-synthetic opioids combine natural and synthetic compounds. Morphine, a prototypical opioid, possesses a...
02:30Metastasis
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

01:15Opioid Analgesics: Synthetic and Semisynthetic Opioids
Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...
01:22Opioid Receptors: Overview
Opioid receptors, including the mu (μ, MOR), delta (δ, DOR), and kappa (κ, KOR) types, belong to the rhodopsin family of G protein-coupled receptors. These receptors are located throughout the central and peripheral nervous systems and in non-neuronal tissues such as macrophages and astrocytes. Opioid receptor ligands can be categorized into agonists or antagonists. Highly selective agonists include [d-Ala2, MePhe4, Gly(ol)5]-enkephalin or DAMGO for MOR, [D-Pen2, D-Pen5]-enkephalin or DPDPE for...
02:38Mitogens and the Cell Cycle
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
01:25Analgesia and Pain Management
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...
